Note that the "executing function" is itself running inside a thread, 
specifically the "main thread".  The other threads are not "below" it in 
any particular sense, more like beside it.  (Or, to put it another way, 
there is no such concept of relative position with threads in Python.)

Here is a basic example of what I mean.

Your code is very close to working already... why don't you just run it 
and observe how it works?

In any case, the answer is "no, time.sleep() affects only the current 
thread".
